  2. Can this script be adjusted to check two sets of check boxes to make sure that at least one checkbox is checked in each set of check boxes?

    Checkbox group 1:
    _option 1
    _option 2
    _option 3

    Checkbox group 2:
    _option 1
    _option 2
    _option 3

    At least one check must be checked in each group above. Is this possible?
